Product Description

Advantages

The intelligent control is realized by using single chip microcomputer and special software.

Accurate discharge control using battery discharge rate correction. Discharge terminal voltage is the control point corrected by discharge rate curve, which eliminates the inaccuracy of single voltage control over discharge and conforms to the inherent characteristics of the battery, that is, different discharge rates have different terminal voltage.

Full automatic control with overcharge, overdischarge, electronic short circuit, overload protection, and unique anti-reverse protection; Above protection does not damage any parts, does not burn insurance;

The serial PWM charging main circuit is adopted to reduce the voltage loss of the charging circuit by nearly half compared with the charging circuit using diode, and the charging efficiency is higher than that of non-pwm by 3% to 6%, which increases the power consumption time. Lifting charge after overdischarge recovery, normal direct charge and automatic control of floating charge make the system with longer service life; It also has high precision temperature compensation.

Direct LED light emitting tube indicates the current battery status to let users know the usage status;

All controls are made of industrial-grade chips (only with I industrial-grade controllers) and can operate freely in cold, hot and humid environments. The crystal timing control is also used and the timing control is accurate.

The setting point of potentiometer adjustment control is cancelled, and the working control points are recorded by E square memory, so that the setting is digitized, and the factors of accuracy and reliability are eliminated because of the deviation of vibration and temperature drift of potentiometer.

With digital LED display and setting, all Settings can be completed by one-click operation, which is extremely convenient and intuitive to use.

Fully sealed waterproof type (-s) has complete waterproof and moisture-proof performance.
